odd colored australorp roo

[Gallus13]

Hi i'm new here and figured this was a good way to have a question answered for me. I recently purchased 3 australorp roos, two of them are normal colored, but my third has a lot of yellow feathering down his head neck and throughout the body. I cant find anything about this online, anyone have any ideas about why hes like this? I unfortunatly do not have a picture at the moment i will have one up in a couple of days tho. Thank you for any help it is much apprecieated.

It means he's not pure Australorp. Check the bottoms of all their feet. Are they pink, white? Or are they yellow? Black Australorps should be solid black, and I've never heard of the gold leakage problem occurring in that breed. . . It sounds to me like a crossbreed.'

btw,
